存储的用于地面空间间接执行的 NT 0 元数据
本地( i.e .) .
This reflects the root extension object of the NGA_gpm_local
glTF 扩展名. 当一个包含这个扩展的模型被装入时,
然后,通过调用可以获取该类型对象
```
const gltfGpmLocal = model.getExtension("NGA_gpm_local");
```
存储类型决定可选属性的存在 :
- When the storage type is `StorageType.Indirect`, then the `anchorPointsIndirect` and `intraTileCorrelationGroups` are present.
- When the storage type is `StorageType.Direct`, then the `anchorPointsDirect` and `covarianceDirect` are present.
